- Linking to Option Trees
- Some Unix-Only methods:
- The Symbolic-Link Way (Unix Only)
- This is a variant of The Put-It-Under-NMROOT Way where the option tree
remains outside of the NeXtMidas installation and a link to it is placed in
$NMROOT/nxm .
- This is extremely common on Linux since the option trees are outside of the
NeXtMidas baseline but still get picked up automatically (without using
OPTION ).
- The directory structure would look like:
$NMROOT/nxm
+- sys
+- myopt -> /home/student/myopt123
+- ucl
/home/student/myopt123
+- cfg
+- prim
+- mcr
+- :
- The Back-Link Way (Unix Only)
- This is a variant of The Normal Way that compresses the directory structure
slightly by using a recursive symbolic link.
- Use of this method is discouraged. This method causes
serious problems for many IDEs (Integrated Development Environments).
- For example:
nM> option myopt /home/student/myopt123
In this example the option tree would be named MYOPT and the
directory structure would look like:
/home/student/myopt123
+- nxm
| +- myopt -> ..
+- cfg
+- prim
+- mcr
+- :
